摘要: 自从Desertification一词引入我国以来,对其概念一直争论不休,尤其含概的范围没有定论,各家所发表的 沙漠化国土面积差额甚大,有几倍之巨,使人莫衷一是,也给有关部门决策带来困难。作者认为中国各种风蚀荒漠 和荒漠化土地的基本数字是清晰的,只是因为对概念的理解不同,导致究竟哪一部分算做沙漠化土地有争论。其 中,最主要的有偏重自然因素的地质历史和偏重人为因素的历史观点的区别。可以通过有益的讨论,统一对概念 的认识,求得一致。另外,作者提出把从17世纪初开始的小冰期,气候干冷.沙尘暴频发作为现代沙漠化过程开始 的观点。

Abstract: The concept of desertification has been a question open to arguments since its introduction to China. Various published areas of China's desertified lands present troubles to policy-makers. In my view, we have got a clear picture of the total area including wind-eroded deserts and desertified lands. However, different understanding of the concept of desertification leads to different category of desertified lands. The most important argument is what is the primary cause of desertification, natural or human factor? Disputes can be avoided by discussion. The author thinks the contemporary desertification dates back to the 17th century when the climate was cold and dry, and dust storms were frequent.

Key words: China, desertification, area, contemporary desertification process
